The analysis unit 3 is configured to perform various analyzes related to respiratory data. FIG. 2 is an explanatory diagram showing an example of the internal structure of the analysis unit 3. As shown in FIG. 2, the analysis unit 3 includes a filter unit 31, a respiration determination unit 32, an inspiratory flow limitation determination unit 33, and an apnea / hypopnea determination unit 34. The determination results determined by the filter unit 31, the respiration determination unit 32, the inspiratory flow limitation determination unit 33, and the apnea / hypopnea determination unit 34 of the analysis unit 3 are acquired and stored in the storage unit 4, and output to the display 5. It is displayed in real time.

The analysis unit 3 may be composed of, for example, a control unit including a memory and a processor. The memory is configured to store computer-readable instructions (programs), for example, a ROM (Read Only Memory) in which various programs and the like are stored, and a plurality of work areas in which various programs executed by the processor are stored. It is composed of a RAM (Random Access Memory) or the like having the above. The processor is, for example, a CPU (Central Processing Unit), an MPU (Micro Processing Unit), and / or a GPU (Graphics Processing Unit). It is configured to execute various processes in collaboration with.

<Filter part>
The filter unit 31 is configured to perform waveform processing of respiratory data. Waveform processing is processing such as removal of unnecessary components for analyzing respiratory data. Waveform processing performed in the filter section is, for example, processing for removing noise from respiratory data, processing for removing high-frequency components, processing for removing low-frequency components, processing for √ (root) amplitude of AD value included in respiratory data, and processing. √ (root) amplitude correction processing may be performed.

Further, the filter unit 31 may be a digital filter. The digital filter may be configured to acquire a digital signal of respiratory data from the input IF2 and perform waveform processing. When the data acquired from the input IF2 is analog, the filter unit 31 may include an A / D conversion unit.

The respiration data subjected to the waveform processing is output to the storage unit 4 and the display 5, and is used for various analyzes in the analysis unit 3.

<Breathing judgment unit>
The respiration determination unit 32 is configured to compare and analyze the respiration data and the first value related to respiration in the breath scan mode, the inspiration scan mode, and the breath search mode. FIG. 5 is an explanatory diagram showing an example of analysis of respiratory data by the expiratory scan mode, the inspiratory scan mode, and the expiratory search mode.

As shown in FIG. 5, the exhalation scan mode is a mode for detecting a second value P3 which is more negative than the first value P1 and is a mode for scanning respiratory data until exhalation is detected. As an example, regarding the respiration waveform which is the respiration data, the predetermined reference value of the respiration waveform is set as the first value P1, and the value smaller than the first value P1 and the arbitrary value P2 or less, which is negative, is the second value. The value P3 can be set, and the exhaled breath can be detected by detecting the second value P3.

The inspiratory scan mode is a mode executed after the expiratory scan mode and is a mode for detecting inspiration. As an example, in the inspiratory scan mode, after the processing of the expiratory scan mode, a value that becomes larger than an arbitrary value P4 that is more positive than the first value P1 (reference value of the respiratory waveform) of the expiratory scan mode is set as a third value. The value P5 can be set, and the intake air can be detected by detecting the third value P5.

The expiratory search mode is a mode in which exhaled air is detected after processing of the inspiratory scan mode to search for the end point of the respiratory waveform used for analysis. In the expiratory search mode, after the processing of the inspiratory scan mode, a value smaller than an arbitrary value P6, which is negative from the first value P1 (reference value of the respiratory waveform) of the expiratory scan mode, is set as the fourth value P7. By detecting this fourth value P7, the exhaled breath indicating the end point of the respiratory waveform can be detected.

As an example of the determination by the respiration determination unit 32, the first value P1 is set to 0 mmH2O with respect to the respiration waveform of the respiration data in which the exhalation is minus and the inspiration is plus, and the value is more negative than the first value P1 in the exhalation scan mode. Breathing is detected by setting an arbitrary value P2 to −0.05 mmH2O and detecting a second value P3 of −0.06 mmH2O. An arbitrary value P4 that is more positive than the first value P1 in the intake scan mode is set to +0.2 mmH2O, and the intake is detected by detecting the third value P5 of +0.25 mmH2O. An arbitrary value P6 which is equal to or less than the first value P1 in the exhalation search mode is set to 0 mmH2O, and the exhalation indicating the end point of the respiratory waveform is detected by detecting −0.01 mmH2O which is the fourth value P7.

The respiration determination unit 32 can calculate the respiratory rate of the subject based on the number of exhalations and inspirations detected by the exhalation scan mode, the inspiration scan mode, and the exhalation search mode at a predetermined time. As an example, when the predetermined time is 30 seconds, the respiratory rate in one minute is increased by doubling the number of times the exhalation and inspiration detected by the exhalation scan mode, the inspiration scan mode, and the exhalation search mode are combined. Can be calculated.

<Intake flow limitation judgment unit>
The inspiratory flow limitation determination unit 33 is configured to determine the presence or absence of inspiratory flow limitation based on the inspiratory waveform of the respiratory data. Inspiratory flow limitation is an index indicating an obstructive apneic hypopnea state.

The inspiratory flow limitation determination unit 33 is based on the presence or absence of a predetermined shape in the inspiratory waveform of the respiration data, and the ratio of the width of the inspiratory waveform and the width of the waveform of the predetermined shape in the inspiratory waveform having the predetermined shape. Therefore, it is configured to determine the intake flow limitation.
The width of the intake waveform indicates, for example, a section between the rising value P8 of the intake waveform and the end P9 of the intake waveform shown in FIG. As an example, when an intake waveform having a dent in a part is detected, the intake flow limitation determination unit 33 determines the intake flow limitation from the width of the waveform occupied by the dent of the intake waveform in the width of the intake waveform including the dent. Judge the presence or absence of.
In the above-mentioned detection of the dent, as an example, the second derivative of the intake waveform is performed, and when the calculation result (amplitude) of the second derivative takes a negative value, it is determined as the dent, and the width of the intake waveform is set. On the other hand, when the width of the waveform of the detected dent exceeds a predetermined threshold, it can be determined that the waveform is a flow limitation waveform.
In addition, the predetermined threshold value can be appropriately set by the user in consideration of individual differences depending on the subject and operational standards at the facility used.

The determination result determined by the intake flow limitation determination unit 33 is output to the storage unit 4 and the display 5.

<Apnea / hypopnea judgment unit>
The apnea / hypopnea determination unit 34 determines apnea or hypopnea when the amplitude of the respiration data at a predetermined time is equal to or less than a predetermined ratio of the average amplitude.

The apnea / hypopnea determination unit 34 may determine whether or not the amplitude of the respiration data in the immediate vicinity of the measurement time of the respiration data is equal to or less than a predetermined ratio of the average amplitude. The latest measurement time of the respiratory data is, for example, from 120 seconds before the measurement time to the measurement time. An example of the amplitude determined to be apnea is 10% or less of the average amplitude, and an example of the amplitude determined to be hypopnea is 50% or less of the average amplitude.
